AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L

Name of the Vulnerable Software and Affected Versions Vim versions prior to 9.0.1499

Description The issue is related to the use of an out-of-range pointer offset in the mb charlen() function in mbyte.c. This can lead to a denial of service. An attacker could exploit this by tricking a victim into opening a specially crafted file, resulting in a crash.

Recommendations For versions prior to 9.0.1499, update to version 9.0.1499 or later to resolve the issue. As a temporary workaround, consider restricting the use of the mb charlen() function in mbyte.c until a patch is available.
